Leak Detection
Is your Pool Losing Water?
Noticing an unexplained spike in your water bill? Is your pool water level dropping faster than normal, losing ½ inch or more per day?
These can all point to a potential pool leak. Other warning signs to watch for include:
- Air entering the plumbing system
- Your pump frequently losing prime
- Visible cracks in the pool or surrounding deck
- Shifting, sinking, or lifting of the deck
- Unusual wet or soggy areas around the pool
- Unexpected liner bubbles, or wrinkles
- Having to top up your pool water more than once a week
How Do We Find a Leak?
Pool leaks can occur in several different areas, and finding the source is the first step toward the right repair. At True North Pool Care, we systematically inspect your pool and plumbing to help pinpoint where water is escaping.
- Pool Liner: Tears, punctures, small holes, or failing seams in a vinyl liner can allow water to escape.
- Underground Plumbing: Cracked pipes, leaking fittings, loose connections, or damaged underground plumbing can cause water loss that may go unnoticed beneath your yard or pool deck.
- Pool Lights: Worn light conduit seals, damaged niches, or leaks where the light conduit connects to the pool can allow water to escape.
- Skimmers & Faceplates: Deteriorated gaskets, loose screws, cracked skimmer bodies, or failing seals around the liner faceplate can cause leaks near the pool wall.
- Return Jets & Fittings: Worn gaskets, cracked fittings, or damaged connections around return jets can allow water to escape behind the pool wall.
- Pool Equipment & Connections: Pumps, filters, heaters, valves, unions, and other equipment connections can develop leaks from worn seals, cracked components, or loose fittings.
At True North Pool Care, we use specialized LeakTrac electronic scanning technology to locate leaks in vinyl pool liners with precision. The LeakTrac system introduces a small electrical current into the pool water and detects the path that current takes when it escapes through a hole or tear in the liner.
As we systematically scan the pool using a specialized electronic probe, the device produces an audible signal that changes as we move closer to the leak. This helps us narrow down the exact location of the problem, even when dealing with small punctures that can be difficult to spot with the naked eye.
By using advanced detection equipment rather than relying on visual inspection alone, we can pinpoint suspected leak locations and help avoid unnecessary guesswork. Once the leak is located, we can assess the damage and determine the best repair solution to help stop water loss and get your pool back in shape.

How we Find Leaks Using Dye Testing?
At True North Pool Care, we use specialized leak detection dye to help identify leaks around pool fittings, returns, skimmers, lights, and other areas where seals or connections may fail. By carefully releasing a small amount of dye near a suspected leak, we can observe how the dye moves in the water and determine whether it is being drawn into a crack, gap, or damaged seal
.
This method allows us to inspect potential problem areas closely, including faceplates, light niches, and plumbing fittings where leaks can be difficult to see. When water is escaping through a compromised seal or fitting, the dye can help reveal the direction of the flow and narrow down the source of the leak.
By combining careful visual inspection with dye testing, we can identify suspected leak locations more accurately and recommend the appropriate repair. Our goal is to take the guesswork out of pool leak detection and help you address water loss before it leads to further problems.

How we Find Underground Plumbing Leaks?
At True North Pool Care, we use professional pressure testing to determine whether your pool's underground plumbing is holding pressure as it should. By isolating individual plumbing lines and pressurizing them to an appropriate testing level, we can assess whether the line maintains pressure or shows signs of a potential leak.
This helps us narrow down which section of the plumbing system may be responsible for water loss.
If a line fails to hold pressure, we take the investigation a step further using the XLT-30 sonic listening device. This specialized equipment detects sound vibrations created by escaping water, helping us narrow down the location of an underground leak without unnecessary digging. By combining pressure testing with acoustic leak detection, we can identify problem areas more efficiently and help determine the best approach for repair.
Our goal is to locate underground plumbing leaks as accurately as possible, minimize disruption to your property, and help you avoid unnecessary excavation and costly repairs.
